I can confirm this. Being an old military telegraphist I too have experience in this. Where a dot lasts 50 - 80 ms the variation is of the order of a few milliseconds, it is surprising how quickly you learn to recognise everyone on the net. I learned to recognise all my colleagues and no two operators ever sounded the same.
Adding to the above poster it should be noted that you had some counter measures when enemy intelligence was clued onto you: use the other hand. The "fist" for left and right hands are very different and would be confused for a different person.
There are tons of stories in the world of Morse code.
